The city is seeing plenty of investment in beer, too. Bell's Brewery Inc., the nation's 13th largest brewery, unveiled its 200-barrel, $20-million brewhouse in Comstock Township this year. Arcadia Brewing Co. is planning a $6.2-million expansion, including plans to locate a brewpub and brewing operations, on the Kalamazoo River.

Other establishments including Olde Peninsula Brewpub & Restaurant, Bilbo's Pizza and Bravo! Restaurant offer their own beers. Boatyard Brewing Co. is setting up shop on the city's north side, and Portage Brewing Co. is getting in the game.

As the craft beer industry evolves in Kalamazoo, it seems fair to ask -- how much is too much? At which point will Kalamazoo hit its craft brew saturation point?
